Mate shoulder barges me and i end up knocking into this lad in yr10
He shouts at me 'tw2t' and i ignore him, next thing I know he's strangling me from behind and punching me in the ribs.

I turn round and left hook him in the face and he gets floored n starts crying.

Then as we sit in our classroom he starts attacking the door with a chair trying to smash the fire glass.
He is trying to get into a room full of yr13/14 sports students who are like a clan and he wants to try and kick the shit outa me, i guess its best for him we closed the door.....

He then tries finding me at lunch and trying to get me into a fight and fails as he gets told to move on by the p.e staff aware of wat happened last lesson.

I got sent home early for my own safety lol! How should I respond tomorrow?

Sad as it is, i don't think there can be a non aggressive solution to this, as it seems that he is hell bent on a confrontation with you, unless someone else annoys him more before he has a chance to have it out with you, and then his attention will be transferred to that person and away from you. The other option is to just get it over and done with, what is the age difference between you, see if the school or local club would allow a proper boxing match between you two, if it is going to happen then try and do it fairly and organised, less chance of assistance from one of his mates.

Yeah but then you went and locked yourself in a classroom, and they had to send you home for your safety.

So, even though you punched him, the fact that he's only a little kid means he done you.

Sorry, that's just how it is. Isn't it, people? I don't make the rules you know.

He's going to give you a Chinese Burn tomorrow. And spit in your dinner.

I once chased an older lad through the school, with a pool cue, cos he nicked me last ciggy off me. Bastid. I would've done him if I'd caught him, but the teachers got me and took the cue away and I had to sit in the medical room for the rest of the day.

Delete him on facebook and send him a series of text messages that are both threatening yet utterly incoherent. (Remember not to use any vowels). That'll show him. I think you can also form a sort of gang on facebook for back up.

An apology and checking he was ok might just have saved you a little trouble but it looks like you've come over all Gaddafi and launched your heavy weapons on the crowd. I reckon it's dangling from a lamppost for the pair of you now.
